I've just ordered a UZB and intend it to replace my Aeotec Z-Stick, solely so that I can use the Z-Way software and API, which looks way better than the half-baked open-source abandonware the Aeotec requires.

So I'm excited about that. But lately I can't stop thinking about the idea of using MQTT as the glue that ties all my devices together — not just the Z-wave ones, but also cheap IoT sensors, various phones, cloud services like Adafruit.IO, etc.

To do that, all I'd need to find (or make) is a bridge that converts Z-Wave events to MQTT feeds, and MQTT fedds into Z-Wave events. As MQTT is quite simple, and Z-Way appears to be reliable and well-designed, this shouldn't be too hard...
